QHow are TV displays measured?

AThe size of a TV is dictated by the diagonal diameter of the screen. This is calculated by measuring from the top left to bottom right of the screen itself - the measurement doesn't include the bezel (the casing around the screen) or any extras - just the screen.

QWhat is the difference between 4k, Full HD and HD Ready?

AThese 3 are a measurement of the "resolution" of a TV - how many pixels the screen can display at once, and therefore how sharp the image is. HD Ready TVs have a resolution of around 1280x720 pixels, whereas Full HD TVs have a resolution of 1920x1080 pixels. 4k TVs have a substantially higher density, being somewhere around 3840x2160 pixels.

The higher the resolution, the sharper the image will be on large screens. An 80 inch TV that only supports HD Ready will look muddy and blurry. On the other hand, 4k resolution will be wasted on a small 3 inch TV, since the screen is too small to make effective use of it.

QWhat is a Smart TV?

AA Smart TV has a net connection, and the ability to run apps like a computer. This means that as well as watching TV, you can use the device to access sites such as YouTube or Netflix, display news updates, browse social media and play music using apps such as Spotify.

QWhat is the difference between LCD & LED TVs?

ALiquid Crystal Displays (LCD) TVs work by shining light through a matrix of coloured liquid cells, whereas Light Emitting Diodes (LED) TVs utilise an enormous amount of tiny LED lights to shine light through, rather than a small number of lamps. LCD TVs still make up the largest amount of TVs on the market, but LED TVs tend to be significantly thinner and lighter, and give a better backlight coverage due to the larger number of lamps.
